This invention relates to the heating of buildings.

'Ihe object of this invention is to provide improvements which will result in a satisfactory l heating of the floors and in some cases the walls of buildings.

The method of heating a oor according to this invention consists in providing one or more heating units extending beneath the surface of the said floor, each of said units having in association a plurality of transversely disposed partitions deflning a plurality of transversely disposed passages through which hot air from the heating unit circulates.

The spaces within which the air circulates may be formed by arranging members which support 'the floor substantially parallel to each other and at an angle to said heating elements, said spaces being either the spaces between adjacent supporting members or the interior of hollow supporting members.

Preferably, but not necessarily, the said spaces have a greater cross-sectional area. at points in the vicinity of the said heating elements than at points remote therefrom.

Where it is desired to heat the walls in addition to the iloor the Wall may be made hollow throughout its length or hollow at intervals only in its length, and the oor passages made to communicate thereinto, the cavity or cavities of the wall being provided with a vertical partition to form an uptake and a downtake, the uptake passage communicating at the bottom with the adjacent fioor passage at a high level therein and the downtake passage communicating with the floor passage at a lower level.

Referring to the drawings filed herewith, which illustrate, by way of example only, two embodi- 'ments of my inventiom- Fig. 1 is a plan of one form of floor constructed in accordance with this invention and shown with the floor surface broken in places;

Fig. 2 is a sectional elevation taken on the line X-X in parallel with the iloor passages; and

Fig. 3 is also a sectional elevation -but'taken on the line A-A laterally of the door passages.

Fig. 4 is a perspective view of a floor beam:

Fig. 5 is a similar plan to Fig. 1 of an alternative form of floor;

Fig. 6 is a sectional elevation thereof on the line Y--Y in parallel with the floor passages;

Fig. "I is a similar view but taken on the line B-B laterally of the floor passages.

Fig. 8 is a sectional detail view showing, to an enlarged scale, the left hand portion of Fig. 2 depicting the junction of the lfloor with a wall.

In` Figs. 1 to 4, a plurality of longitudinally aligned iloor beams 2, 2 are placed at distances apart to form longitudinal passages 3, 3 between '5 them and openings 4, 4 at their ends, the beams being supported at their ends on raised surfaces 5, 5 of a foundation 6 and themselves. supporting a iloor surfaceof longitudinal slabs 1, I provided one to each of the passages 3, 3 with their ends 10 spaced apart and adapted to support laterally disposed removable slabs 8, 8. 4

Disposed laterally of the passages 3, 3 at the ends thereof and between the ends of the beams 2. 2 are placed longitudinally aligned heating ele- 15 ments 9, 9 through which steam or hot water 4is passed and which are supported on small stands or feet I0, I0, adjacent heating elements being connected by ilow and return pipes II and I2, respectively, conveying the heating medium from 20 flow and return conduits I3 and I4, respectively.

The beams 2, 2 are provided with side webs I5 of the requisite form to support inclined subfloor members I6, I6 and insulation Il, I1 in each passage so as to give each of such passages 3, 3 25 a form having the least depth at their centres and increasing gradually to the greatest depth at their ends. The adjacent lower ends oi the Subfioor members I 6, I6 are spaced apart and rest upon the supports 5, the insulation I1, I1 being 30 similarly arranged so that the openings 4 are left free and open.

The removable slabs 8, 8 serve as inspection covers giving access to the heating elements 9. 3 and the said heating elements'are of greater 35 height than width in cross section and are so arranged with respect to the passages 3 that the said passages are confronted by the major surfaces of the heating elements whereby heat is radiated into the passages from the major sur- 40 faces of the said heating elements.

Where it is desired to heat a wall in addition to the floor, the passages 3, 3 adjacent the wall I(not shown) are provided with the sub-floor members I6, I6 terminating at the wall at or 45 about their highest point. In the wall is provided, in some cases, one to each of several passages 3, 3 or, in other cases, one to a plurality of adjacent passages 3, 3 an upright box-like casing as shown at IB and I9, respectively. This casing is provided with an uptake 20 at the front and a downtake 2| .at the rear formed by a partition 22, the lower end of the uptake 20 communicating with an adjacent passage 3 at the upper part thereof and the downtake communiing elements 5,13 circulates in the passages 3, 3

or passes out-from'the outer ends thereof to rise throughthe uptake 20 and returns as colder air .ici

through the downtake 2|, spaces 23 and slots 24 tpfthe inner ends ofthe passages 3, in each case returning to the heating elements s, s to become heated again, whereby a continuous circulation is obtained, so that heat is conveyed to the underside of the oor over a large area, vizt-over substantially the Whole area thereof except at the places occupied by the floor supporting members, or both to the iloor and to the wall.

Figs. 5, 6 and 7 show an alternative construction of heated iloor which is similar in some respects to that of Figs. 1 to 4, but in this case floor supporting beams 25, 25 consisting of tubular blocks are provided and placed side by side except for a small space 26 between them for the reception of groutlng material for joining them together.

Theblocks are supported on the foundation 21 and themselves support slabs .28 forming the fioor surfaces. The blocks are spaced apart at their ends to provide the spaces for the heating elements 9, and the hollows of the blocks form longitudinal passages 29, 29 heated by the said elements. Where a wall is also to be heated in this construction of floor, the box-like casings I8 or I9 shown in Figs. 1 to 3 may be again employed the uptakes 20 of which communicate at their lower ends at a high level in the passages and the downtakes 2l returning to communicate also in the passages but at a lower level whereby a continuous circulation of, heated air takes place from theiioor and through the casing i8 or IS.

The heating elements are supported and connected up similar to those in Figs. l to 3.

What I claim and desire to secure by Letters Patent is:

1. A floor having in association heating means and comprising a plurality of supporting members forsaid oor defining a plurality of passages. at least one heating unit arranged transversely with respect to said supporting members and adapted to cause hot air to traverse said passages longitudinally thereof, said passages having a greater cross sectional area in the vicinity of said l heating unit and a less cross sectional area at-a point remote from said heating unit.

2. A oor having in association heating means and comprising a plurality of supporting members for said floor dening a plurality of passages, a heating unit having a greater height than width in cross section arranged transversely with respect to said supporting members, said passages being confronted by the major heating surfaces of said heating unit, said major surfaces being dened by the said greater height of said unit.'

3. A iioor and a wall thereto having in association heating means and comprising a plurality of supporting members for the floor defining a plurality of passages thereunder, uptake and downtake passages in the wall communicating with at least one of said passages under the iioor, a heating unit having a greater height than width in cross section arranged transversely with respect to the floor supporting members, said iloor passages being confronted by major surfaces of said heating units, said major surfaces being dened by the said greater height of said units.
